A plication filed June 14, 1909. Seria1'No. 2502',132.f

To all whom it may concern: a Be it. known that I, SAMUEL G. Goss, a citizen of the Vnited States, residing at .Chieago, in the county of Cookand State of Illinois, have invented certain new anduseful Improvements in Combined Plate Shaving, Trimming, and Tail-Cutting Machines, of which the following is a specification, reference being bad to the accompanying drawings.

My invention relates to combined plateshaving, trimming and tail-cutting machines for stereotype :plates, and its object is'to produce a new. an improved machine, in which the tails of the stereotype plate may be severed, the edges trinmied and the plate shaved, andat the same time the heated plate cooled in the same machine'du'ring the process of shaving, ming."

In the drawings,-Figure 1 is 'a'side'elevation; Fig. 2=is an end elevation-seeirfrom the rightin Fig. -l-g'Fig. '3 is a horizontal "tail cntting and "l trimsection on line 3-3 of Fig.1; Fig. 4 is a do taiL'being a vertical section on lineH of Fig. 1; Fig. 5 is a detail, beinva vertical section on line 5-5 of 1; ig.'-6 is an enlarged detail, being aview of the'trimmin -blade; Fig. 7 is a detail, being a view of a portion of one end of a supporting shaft with the rotatable sleeve removed to show the circumferential grooves for admitting preferably formed of two portions,+- base portions 13, which'arebolted to, the frame,

and semi-circular ring portions 14, which are bolted in the base portions 13. These ri v-supports rotatably carry a drum' 15, which 1s cylindrical in form, but having-a cut-away portion 1!) intermediateitsend's, and is adapted to rotatably fit the ring-supports 12 so as to rotate therein.

Upon one end of the drum 15 is mounted a gear-ring 16. As is bests hown in Figs. and 4, theinterior surface of the drum ,15

as 31,,on, the

the last passage on the opposite side, as more fully hereinafter described.

34 indicates a. shaft, which is supported in suitable collars 35-36, respectively, mounted on standards 37-38 and suitably supported upon the frame of the-machine. The shaft 34; is located centrally of the drum 15 and projects beyond it at each end, as is best shown in Figs. 1 and 3. At one end the drum 15" is pro'vided with a bearing 39, which is supported centrally of the drum by means of arms 40. The bearing 39 and arms 40 are preferablv formed integral with the drum. The bearing 39 is provided with a peripheral flange 39 and is centrally bored to receive the shaft 34, which is cylindrical in section to permit the revolution of the drum thereon. At one end-the left-hand end" in Figs. 1 and 3-t-he shaft 34 is provided with two passages 41-42 extendin inward from the end of the shaft 34 towar the adjacent end of the drum. ends the passa es 41 and 42oturn and open upont-h'c exterior periphery of the shaft 34,

respectively, into the peripheral grooves 43 and 44 on the shaft 34.

45 indicates a collar, wh ch is gournaled on the shaft 34 and is provided at its inner end with a .rabbeted portion &6, which is adapted to tit under the peripheral tlange 39 of the bearing head 39.

47 indicates packing between the flanges 39 and the shaft 34. and the rabbeted portion of the collar 45. The collar 45 is provided upon opposite sides with openings 48 "and 49, which register, respectively, with the peripheral grooves 43 and 44 on the shaft 34. The-outer end of the collar 15 is rabbeted out on its interior eripherally so as to form an opening into w ich fits a collar 50 with a packing 51 interposed. The other end of the shaft 34 is provided with a longitudinal passage 52 extending inward from the right-- hand end of the shaft 34 into the interior of the drum 15. At that part of the passage 52 which lies within the drum 15 it is provided with a plurality of openings 53, which, as is best shown in Fig. 8, are narrowed at their outer ends and open upon the periphery of the shaft 34 so as to permit the passage of the cooling fluid passed into the passage 52, as above described, upon the inner periphery of the late when in position in the cylinder, as is best shown in Figs. 2 and 8.

55 indicates a tank adapted to contain a supply of the cooling fluid, preferably under compression, and led into the tank from any suitable source through supply pipes 56 -4 7 controlled by a valve 58. The cooling fluid may be cold air under compression or cold water forced into the tank or the apparatus above described, or any other suitable fluid adapted for cooling the ap aratus.

59 indicates a pipe, whic opens into the At the inner.

tank at one end, and at the other end is connected by a suitable screw-threaded connection. as 60, with the passage 42 and serves as an inlet passage for the fluid from the tank into the drum.

(31 indicates a pipe, which is screw-tlneaded into the opening 4.) at one end, and at the other end opens by any suitable connection into the first ot' the series of passages 33 upon the righl hand side of Fig.

62 indicates a pipe. which. by any suitable connection, is connected at one end with thelast of the passages 33, and at its other end h any suitable connection opens into the passage ts in the collar 45.

63 indicates a discharge pipe, which is screw-threaded by any suitable connections into the outer end of the opening 41 and serves to discharge the fluid after passing through the drum.

64 indicates a pipe leading from'the tank 55 to the outer end of the passage 52, with which it is connected inany suitable manner. The pipe 64 is controlled by a suitable valve 65, by means of which a cooling fluid may be admitted from the tank 55 through the pipe 64 into the opening 52 and thence sprayed, as indicated in Fig. 2,. upon the inner surface of the plate.

66 indicates a shaving-knife, which is secured to suitable brackets 67 projecting from and preferably formed integral with the shaft 34. The shaving-knife (it; is

mounted on the brackets 67 so that its cutting edge may bear-upon the usual ribs on the interior surface of the plate when the drum is rotated and shave them so that the plate may be of the proper thickness.

68 indicates a trimming-knife, which is mounted upon one of the brackets 67 and secured thereto and is provided with a beveled cutting edge 69 conforming to the bevel of the edge of the plate. The cutting edge is located so as to bear upon the inner edge of the plate, when the drum is rotated, to trim it to asuitable bevel.

70 indicates a rotary cutter having at hereled cutting periphery corresponding to the desired bevel upon the plate and secured to a counter-shaft 71 which is journaled in suitable bearings, as 72, on the frame of the machine. The outer end of the countershaft 71 is provided with a pulley 73, which, by means of a belt 74, is driven from the pulley 32 on the counter-shaft 3O.

17 indicates the stereotype plate, and B the tail-piece of said plate usually left after the casting of the plate in the ordinary manner.

The operation of the devices is as follows: The plate being pushed into the drum from its open end, its edges resting on the bearings 18, is held thereby closely to the interior surface of the drum. The valves being opened, the cooling fluid, which may, as has been said, be either cold air, cold water, or any other suitable cooling fluid. flows through pipe 59, cored-out openings 33 into the drum 15, out through pipe 62 and pipe 63, keeping the surface of the drum constantly cold and chilling the plate. Atthe same time the cooling fluid-the valve 65 being open passes through the pipe 64 into the other end of the shaft 3&- and through passages 53 and is sprayed upon the under surface of the plate. The clutch-members 2223 being thrown into engagement by the lever 26, the drum is caused to slowly rotate, bring the plate by its rotation into engagement with the cutting edge of the shaving-knife 66, shaving the interior of the plate, as it rotates, to a proper thickness. The trimming-knife 68 also operates to trim the inner beveled edge of the plate, and the rotary cutter 70, driven as above described, severs the tail-piece from the plate as the rotation of the drum brings the plate into operative relation with the rotating cutter,the rotating cutter at the same time trimming the edge of the plate. As the drum reaches its original position, its rotation is stopned by throwing the clutch-members out of engagement, and the plate, cooled during the trimming, shaving and tail-cutting operation, is ready for removal and in shape to be immediately transferred to the operating press.
